Generate Typescript types from a live Postgres database.

This is for people who don't like ORM's but who do like intellisense and type checking for their database access code.

See the documentation [here](https://kristiandupont.github.io/kanel)

Introduction to the idea is outlined [here](https://medium.com/@kristiandupont/generating-typescript-types-from-postgres-48661868ef84).

## Usage

Install with:

```bash

$ npm i -D kanel

```

To run, make sure you are in a folder that has a `.kanelrc.js` configuration file and that your database is running, and type:

```bash

$ npx kanel

```

## Programmatical usage

Example of running generation from code:

```typescript

import { processDatabase } from "kanel";

import config from "./kanelrc";

async function run() {

  await processDatabase(config);

}

run();

```

## Example

To see an example of the result, check out the [/example](example) folder. It uses the [Sample Database](https://www.postgresqltutorial.com/postgresql-sample-database/) from www.postgresqltutorial.com.

If you want to learn about how I use this together with [tRPC](https://trpc.io/) to create end-to-end type safety with PostgreSQL as the source of truth, check out my course on Newline:
